Preliminary report: Surgical outcomes following genitoplasty in children with moderate to severe genital atypia

Genito-urinary Reconstruction in Female Children With Congenital Adrenal Hyperplasia: Favorable Surgical Outcomes can be Achieved by Contemporary Techniques and a Dedicated Multidisciplinary Management

INTRODUCTION

Congenital adrenal hyperplasia (CAH) is the most common cause of genital atypia in females. A dedicated multidisciplinary team (MDT) should be included for an optimal management. Here, we aimed to review our surgical experience and to assess long-term urinary, gynecological and endocrine outcomes after primary genitoplasty in this specific cohort.

METHODS

Patients born with CAH and who underwent feminizing genitoplasty in our institution were retrospectively identified (2001-2021). We analyzed patients' characteristics, intraoperative details, and postoperative urinary, gynecological, and endocrine outcomes.

RESULTS

Forty patients were included and followed-up for a median (IQR) time of 7 (1-19) years. Thirty-eight (95%) had 21-hydroxylase deficiency. After multidisciplinary decision and written consent from patient and/or family, a single-stage reconstructive surgery was performed at a median age of 10 (3-165) months. Median length of hospital stay was 5 (1-7) days. Procedures were: PUM (N = 35 (87.5%)), TUM (N = 3 (7.5%)), urogenital mobilization was unnecessary in 2 (5%). Reduction clitoroplasty was done in 33 (82.5%) patients. Only 3 (7.5%) experienced significant Clavien-Dindo complications requiring additional surgery during the follow-up period. Recurrent urinary tract infections (UTI) occurred in 6 (15%), one required ureteric reimplantation for symptomatic high-grade vesicoureteric reflux. All patients over 3 years were toilet-trained without incontinence. Severe vaginal stenosis occurred in 1 (2.5%) patient. In patients who achieved puberty, 6/9 had vaginal calibration at a median age of 17.3 (16-21) years without detected stenosis. One (2.5%) had major hypertrophy of the right labia minora requiring labiaplasty. Nine (22.5%) reached puberty. Two (5%) patients developed acne/hirsutism. Short stature was noted in 11 (27.5%) and obesity in 18 (45%).

CONCLUSION

Based on our contemporary series, genitourinary reconstructive surgery for female patients born with CAH is technically feasible and safe with a low complication rate. A regular follow-up with a MDT to assess long-term complications is necessary, and it is vital to inform patients and families about the different management options with all the risks and benefits of surgery.

Trajectories of illness uncertainty among parents of children with atypical genital appearance due to differences of sex development

OBJECTIVE

The present study aimed to identify distinct trajectories of parental illness uncertainty among parents of children born with atypical genital appearance due to a difference of sex development over the first year following diagnosis. It was hypothesized that four trajectory classes would emerge, including "low stable," "high stable," "decreasing," and "increasing" classes, and that select demographic, familial, and medical factors would predict these classes.

METHODS

Participants included 56 mothers and 43 fathers of 57 children born with moderate to severe genital atypia. Participants were recruited from eleven specialty clinics across the U.S. Growth mixture modeling (GMM) approaches, controlling for parent dyad clustering, were conducted to examine classes of parental illness uncertainty ratings over time.

RESULTS

A three-class GMM was identified as the best-fitting model. The three classes were interpreted as "moderate stable" (56.8%), "low stable" (33.0%), and "declining" (10.3%). Findings suggest possible diagnostic differences across trajectories.

CONCLUSIONS

Findings highlight the nature of parents' perceptions of ambiguity and uncertainty about their child's diagnosis and treatment the year following their child's birth/diagnosis. Future research is needed to better understand how these trajectories might shift over the course of the child's development. Results support the development of tailored, evidence-based interventions to address coping with uncertainty among families raising a child with chronic health needs.

Neurological Considerations for "Nerve-Sparing" Cosmetic Genital Surgeries Performed on Children with XX Chromosomes Diagnosed with 21-Hydroxylase Congenital Adrenal Hyperplasia and Clitoromegaly

Congenital adrenal hyperplasia (CAH) is most often caused by adrenal deficiency of 21-hydroxylase (21-OH). The resulting increase in androgens can cause clitoromegaly in fetuses with XX chromosomes. 21-OH CAH is the most common reason for cosmetic clitoroplasty in childhood. "Nerve-sparing" (NS) clitoral reduction surgeries are described as offering optimal cosmesis, while sparing sensation and nerve function. The methods used to demonstrate NS surgery efficacy, however, such as electromyography and optical coherence tomography, do not evaluate the small-fiber axons that comprise the majority of axons in the clitoris and that transduce sexual pleasure. Although some data show sparing of a portion of the main dorsal nerve trunk of the clitoris, the overall neurobiological consequences of elective clitoral reductions have received little attention. NS surgeries remove dorsal nerve branches that transduce sexual sensation, as well as the corpora cavernosa and cavernous nerve, which provide clitoral autonomic function. While most outcome studies focus on surgeons' perceptions of cosmetic results, studies that assess small-fiber function indicate significant nervous system and sexual impairment. Studies assessing children's clitoral function after surgery with vibrational testing have been ethically condemned. Decades of advocacy against medically unnecessary childhood genital surgeries have highlighted the subsequent physical and psychological harm. Recent studies with CAH patients indicate gender diversity and a lower prevalence of female gender identification than is often cited to justify feminizing surgery. The most effective and ethical NS technique for CAH may be acceptance of gender, sexual, and genital diversity as the infant develops into childhood, adolescence, and adulthood.

Clinical guidelines for the diagnosis and treatment of 21-hydroxylase deficiency (2021 revision)

Congenital adrenal hyperplasia is a category of disorders characterized by impaired adrenocortical steroidogenesis. The most frequent disorder of congenital adrenal hyperplasia is 21-hydroxylase deficiency, which is caused by pathogenic variants of CAY21A2 and is prevalent between 1 in 18,000 and 20,000 in Japan. The clinical guidelines for 21-hydroxylase deficiency in Japan have been revised twice since a diagnostic handbook in Japan was published in 1989. On behalf of the Japanese Society for Pediatric Endocrinology, the Japanese Society for Mass Screening, the Japanese Society for Urology, and the Japan Endocrine Society, the working committee updated the guidelines for the diagnosis and treatment of 21-hydroxylase deficiency published in 2014, based on recent evidence and knowledge related to this disorder. The recommendations in the updated guidelines can be applied in clinical practice considering the risks and benefits to each patient.

Post-operative complications following masculinizing genitoplasty in moderate to severe genital atypia: results from a multicenter, observational prospective cohort study

INTRODUCTION

Differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. A phenotype of severe genital atypia in patients raised as male is a relatively rare occurrence and standards for management are lacking. Decision making for early surgical planning in these rare cases includes, but is not limited to, degree of atypia, location of testes, and presence of Mϋllerian remnants. In this study we describe surgical approaches and short-term outcomes for masculinizing genitoplasty in moderate to severe genital atypia in young patients raised male, for whom parents opted for early surgery.

METHODS

This NIH-sponsored study is an ongoing, observational, multicenter investigation assessing medical, surgical and psychological outcomes in children and their parents affected by atypical genitalia due to DSD. Participants were prospectively enrolled from 12 children's hospitals across the United States that specialize in DSD care. Criteria for child enrollment were a Quigley score of 3-6 in those with a 46, XY or 45,X/46, XY chromosome complement, age <3 years with no previous genitoplasty; patients were included independent of whether genitoplasty was performed. Cosmesis was graded according to a 4-point Likert scale and complications per the Clavian-Dindo classification.

RESULTS

Of the 31 participants, 30 underwent hypospadias repair and 1 patient did not undergo a genitoplasty procedure. The majority of participants (22) received a staged hypospadias repair. Seventeen complications were identified in 12 of the 31 children (41%) at 12 months of follow up. Glans dehiscence and urethrocutaneous fistula were the most common complications. Orchiopexy was performed in 14 (44%) and streak gonads were removed in 4 (13%) participants. Both parents and surgeons reported improved cosmesis after surgery when compared to baseline.

CONCLUSION

Genitoplasty was chosen by parents for the majority of children eligible for study. No single surgical approach for masculinizing moderate to severe genital ambiguity in young patients with 46, XY or 45,X/46, XY DSD was adopted by all surgeons. Complications occurred in 41% of those who underwent genitoplasty for severe hypospadias. Overall, appearance of the genitals, as determined by parents and surgeons, improved following genitoplasty. Outcomes of early genitoplasty are needed to guide families when making decisions about such procedures for their young children.

Post-operative complications following feminizing genitoplasty in moderate to severe genital atypia: Results from a multicenter, observational prospective cohort study

Disorders/differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. While there remains controversy around the traditionally binary concept of sex, most patients with DSD are reared either male or female depending on their genetic sex, gonadal sex, genital phenotype and status of their internal genital tract. This study uses prospective data from 12 institutions across the United States that specialize in DSD care. We focused on patients raised female. Eligible patients had moderate to severe genital atypia (defined as Prader score >2), were ≤2 years of age at entry, and had no prior genitoplasty. The aim of this study is to describe early post operative complications for young patients undergoing modern approaches to feminizing genitoplasty. Of the 91 participants in the cohort, 57 (62%) were reared female. The majority had congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (n = 52), 1 had ovo-testicular syndrome, 2 had mixed gonadal dysgenesis and 2 had partial androgen insensitivity syndrome (PAIS). Of the 50 participants who received early genitoplasty, 43 (86%) had follow-up at 6-12 months post-surgery. Thirty-two participants (64%) received a clitoroplasty, 31 (62%) partial urogenital mobilization and 4 (8%) total urogenital sinus mobilization. Eighteen percent (9/50) experienced post-surgical complications with 7 (14%) being rated as Clavien-Dindo grade III. Both parents and surgeons reported improved satisfaction with genital appearance of participants following surgery compared to baseline. This information on post-operative complications associated with contemporary approaches to feminizing genitoplasty performed in young children will help guide families when making decisions about whether or not to proceed with surgery for female patients with moderate to severe genital atypia.

[Disorders of sex differentiation: state of the problem 15 years after the Chicago consensus]

It is well known that the nomenclature and classification were changed in 2005 at the international consensus conference on intersex disorders, held in Chicago, where, among others, the following recommendations were proposed: (1) all children should be assigned a gender identity, and this should be done as quickly as possible, taking into account the time required for the examination. (2) all infants with congenital adrenal hyperplasia and 46,XX karyotype, including those with pronounced masculinization, must be raised as women. (3) Surgical treatment should be performed early and in cases of feminizing genitoplasty, clitoral reduction should be performed simultaneously with reconstruction of the urogenital sinus (separation of the vagina and urethra). An analysis of contemporary literature shows that all these theories, proposed 15 years ago at the Chicago meeting, failed to stand the test of time. New nomenclature and classification are constantly being revised. Currently, many groups of patients want to abolish the term &laquo;sexual maturity disorders.&raquo; Recommendations regarding gender reassignment and appropriate early surgical treatment have been completely ignored in some countries. All this was largely facilitated by the confrontational activities of a number of support groups.

Early Feminizing Genitoplasty in Girls with Congenital Adrenal Hyperplasia (CAH)-Analysis of Unified Surgical Management

AIM

To analyze a single-centre experience in feminizing genitoplasty in virilized girls with congenital adrenal hyperplasia (CAH).

METHODS

Review of medical records of all 46, XX CAH patients undergoing single stage feminizing genitoplasty between 2003 and 2018 was performed.

RESULTS

A total of 31 girls aged from 4 months to 10 years were included in the study. The majority (n = 26/31, 84%) were operated before 2 years of age (median 8 months). External virilization was rated as Prader 3 (n = 7/31), Prader 4 (n = 21/31) and Prader 5 (n = 3/31). The urethrovaginal confluence location was low in 19 and high in 12 girls with a percentage distribution similar in Prader 4 and 5 (p > 0.05) but significantly different in Prader 3 (p = 0.017). The follow-up ranged from 12 months to 15 years. All parents assessed the cosmetic result as satisfactory. Perioperative complications occurred in two patients and included rectal injury (n = 1/31) and prolonged bleeding (n = 1/31). Three patients developed late complications including labial atheromas (n = 2/31) and vaginal stricture requiring surgical dilatation (n = 1/31). Low confluence did not decrease the risk of complications.

CONCLUSIONS

Early feminizing genitoplasty in girls with congenital adrenal hyperplasia, irrespective of virilization severity, gives satisfactory cosmetic results and is characterized by low and acceptable surgical risk. Nevertheless, the most important determinant of the effectiveness of such management would be future patients' satisfaction.

Individualized care for patients with intersex (disorders/differences of sex development): part I

The care of individuals with disorders/differences of sex development aims to enable affected individuals and their families to have the best quality of life, particularly those born with severe genital ambiguity. Two of the biggest concerns for parents and health professionals are: (1) making a gender assignment and (2) the decisions of whether or not surgery is indicated, and if so, when is best for the patient and parents. These decisions, which can be overwhelming to families, are almost always made in the face of uncertainties. Such decisions must involve the parents, include multidisciplinary contributions, have an underlying principle of full disclosure, and respect familial, philosophical, and cultural values. Assignment as male or female is made with the realization that gender identity cannot be predicted with certainty. Because of the variability among those with the same diagnosis and complexity of phenotype-genotype correlation, the use of algorithms is inappropriate. The goal of this article is to emphasize the need for individualized care to make the best possible decisions for each patient's unique situation.

Management of 46,XY Differences/Disorders of Sex Development (DSD) Throughout Life

Differences/disorders of sex development (DSD) are a heterogeneous group of congenital conditions that result in discordance between an individual's sex chromosomes, gonads, and/or anatomic sex. Advances in the clinical care of patients and families affected by 46,XY DSD have been achieved since publication of the original Consensus meeting in 2006. The aims of this paper are to review what is known about morbidity and mortality, diagnostic tools and timing, sex of rearing, endocrine and surgical treatment, fertility and sexual function, and quality of life in people with 46,XY DSD. The role for interdisciplinary health care teams, importance of establishing a molecular diagnosis, and need for research collaborations using patient registries to better understand long-term outcomes of specific medical and surgical interventions are acknowledged and accepted. Topics that require further study include prevalence and incidence, understanding morbidity and mortality as these relate to specific etiologies underlying 46,XY DSD, appropriate and optimal options for genitoplasty, long-term quality of life, sexual function, involvement with intimate partners, and optimizing fertility potential.

Psychological perspectives to early surgery in the management of disorders/differences of sex development

PURPOSE OF REVIEW

The review focuses on genitoplasty, performed on young children with disorders/differences of sex development (DSD) to 'typify' ambiguous external genitalia and intended to result in either male or female-appearing genitals. Consensus on whether or not early genitoplasty is optimal or appropriate has yet to be achieved. This article reviews arguments in favor of early surgery as well as those disputing their justification.

RECENT FINDINGS

Arguments supporting early genitoplasty include the assumption that a child's genital anatomy should match their gender of rearing for optimal psychosocial development and that outcomes are better physically and psychologically than when surgery is deferred. Those disputing their justification argue that they deny patients the right to participate in irreversible decisions related to anatomy and gender, revoke the possibility of an open future, and violate basic human rights. Clinical management includes recommendations for interdisciplinary care integrating psychologists, and shared decision-making processes to assist families in carefully considering options.

SUMMARY

Early genital surgery in DSD care is controversial with compelling arguments put forth by both proponents and opponents. Relevant issues can be examined from ethical, psychological, cultural and medical perspectives - all of which need to be accounted for in both research and standard of care development.
